Description

Coupling member and coupling system for rotatively coupling an arm member to a column member, in particular for coupling a monitor arm member to a support member

This creation is generally about a coupling used to pivotally couple an arm to a post, especially a coupling used to couple a monitor arm to a support, such as a monitor arm to a table Couplings for pillars of type monitor brackets or wall monitor mounts.

Monitor supports are well known and are used to position a monitor (typically a flat panel display) at a desired viewing position on a table or wall. In general, a monitor support member includes a pillar member extending along a longitudinal axis, a monitor arm member for supporting the monitor radially outward with respect to the longitudinal axis of the pillar member, and a coupling member, the monitor The arm member is rotatably coupled to the post member with the coupling member when in use. For example, the post can be supported on a table or wall directly by, for example, a clip or plate, or indirectly by another arm.

The monitor stand actually has a fairly complex structure and can contain several posts. The desk monitor stand may, for example, include a first post The first pillar is implemented as a main pillar, which is supported by the table, and rotatably carries the monitor arm by a coupling member. Such a first post may include a mounting rail so that, in addition to the angle of rotation of the monitor arm, the position of the arm on the longitudinal axis of the post may also be set to set the monitor at The desired height above the table. The desk monitor bracket may also include a post, which can be implemented as an intermediate post in the case of a connected monitor arm, for example, where the connected monitor arm includes two arms, which can be borrowed It is rotatably connected to a common post by a coupling, for example to increase the reach of the bracket.

Also, since the monitor stand can have multiple monitor arm pieces, for example, a single post piece that is actually the main column can carry two or more separate arm pieces to allow different monitors carried on the stand Each can provide services to another table, or allow more monitors to be placed on a composite viewing plane of a single table, so the organization of the monitor can be further complicated. The posts need not always extend straight, but may also extend laterally, for example in the case where the monitor support is implemented as a wall mount or (transverse) pole.

In general, when manufacturing or setting up, the monitor support needs to be restructured so that its arm can serve a specific area, for example, depending on the position of the stand on the table. This prevents the monitor from touching the back wall or the left or right wall during adjustment. It also prevents the monitor from reaching outside the service area and entering another service area, for example, the service area next to the table. This can generally be accomplished by using complex mechanisms and specific components to control the rotation of the arm around the post.

Often existing monitor supports need to be restructured so that their arms can serve new service areas, for example, when the stand is moved to a different location on the table, when it is moved to a different table, or when the stand is When restructured to carry a different number of arms and / or monitors.

Because of this complexity, the monitor arm brackets are quite expensive to manufacture, and (re) structuring involves quite complex operations, which often require tool and / or component replacement. The purpose of this creation is to provide a coupling member for rotationally coupling an arm member to a column member, and in particular, a column member for rotationally coupling a monitor arm member to a monitor support member. Connectors can alleviate these problems. In particular, the purpose of this creation is to provide a coupling member for convolutively coupling the arm member to the post member to allow the configuration and reconfiguration in simple operation without the need for component replacement and / Or tools, and they do n’t cost a lot of money in manufacturing. In addition, this creation provides a coupling member for rotationally coupling the arm member to the pillar member. The coupling member works with the pillar member as a coupling component through a pillar member interface when in use, and by The arm piece interface works together with the arm piece as a coupling assembly, wherein the coupling piece including its interface provides a limited relative rotational movement between the arm piece and the post about a swing axis, the swing axis being along It extends towards the longitudinal axis of the post, wherein the limited rotational movement is provided in a rotation region, which corresponds to a single rotation about the longitudinal axis.

By providing the coupling and / or its interface with limited and relative rotational movement in a rotational area corresponding to a single rotation, a simple and permitting easy restructuring can be obtained.

The limited relative rotational movement may be provided at one of the interfaces or both of the interfaces. Alternatively or additionally, the limited relative rotational movement may also be provided within the coupling itself.

The limited relative rotational movement provided by the coupling and its interface may be provided in a rotary sub-area, which is less than a single rotation in one orientation of the coupling, and through the coupling With respect to the adjustment position of the member relative to the arm member and / or the column member about its rotation axis, the rotary sub-region corresponds to a single rotation. In this case, the coupling member may not complete a complete rotation in a specific orientation, but promote the complete rotation by adjusting the orientation (selecting a work area from a rotary sub-region corresponding to the complete rotation as a whole).

The single rotation referred to here is an approximately complete rotation, which preferably corresponds to 360 degrees, but may actually be slightly larger or slightly smaller, for example, larger than 330 or 345 degrees, and smaller than 375 or 390 degrees.

The column member interface and the arm member interface may include a rotation restricting member which, when in use, restricts the interface from rotating with respect to its coupling assembly about a rotation axis that extends along the longitudinal axis of the column member . At least one of the pillar member interface and the arm member interface may include a non-stationary rotation restriction member that, when in use, couples its coupling assembly to a limited rotation stroke so that the arm member and the column Limited relative rotation between the pieces around the axis of rotation, By providing a coupling (which includes a rotation restriction on both the post and the arm interface, at least one of which is non-fixed and has a limited stroke), the arm can be relatively easily controlled around the post And the use of fairly inexpensive components to simplify (re) structure.

The coupling may include a substantially cylindrical body portion extending along the axis of rotation. The surface of the radial inner sleeve of the body portion may be a component of the post interface, and the surface of the radial outer sleeve of the body portion may be a component of the arm interface. In this way, the coupling member can form a bushing disposed between the pillar member and the monitor arm member. This allows simple and elegant construction. Such coupling bushings can be manufactured from plastic materials, for example, by injection molding. The coupling bushing may be a single part, but may also be composed of several parts. By arranging the other of the pillar interface and the arm interface with a fixed rotation restricting member (which is rotatably coupled to its coupling assembly to prevent relative rotation about the swivel axis), the coupling is coupled The pieces can be provided with simple operation, and with this coupling piece, the (re) structuring can be intuitive.

By arranging both the column interface and the arm interface to include non-fixed rotation restriction members, a coupling member can be provided. With the coupling member, it is quite easy to gather limited free travel at the interfaces of the two Ground to obtain a single, complete 360-degree rotation maneuver. Both non-stationary rotation restrictors may then have the same swivel axis.

By arranging the rotation limiter to adjust inversely between the non-fixed and fixed positions, the (re) structure can be further simplified.

By arranging the rotation restricting member to include the protruding member, construction and (re) structuring can be further simplified. The protrusion may extend radially with respect to the swivel axis, for example, radially inward when disposed at the post interface, and radially outward when disposed at the arm interface. The projection may extend parallel to the swivel axis. Gracefully, the protrusion can be implemented as a tab, which can be configured to couple the corresponding slot in the coupling assembly at the interface. The slot may also extend parallel to the axis of rotation. The slot has matching dimensions in the direction of rotation about the longitudinal axis to receive the convex member without play to form a fixed rotation restricting member. Alternatively, the slot may be oversized in the direction of rotation to receive the convex member without movement to form a non-fixed rotation restricting member with a limited stroke.

The coupling member may include at least two protruding members, each of which has a slotted hole to increase stability. Gracefully, more slots can be provided than the protrusions, so that each protrusion can choose one of the more slots to be coupled. This facilitates the (re) structuring of the coupling without the need for replacement parts.

In particular, the coupling member may be configured to couple the column member to the arm member with respect to the arm member and / or the pillar member in two or more separate rotational orientations about the swivel axis, each Each orientation allows a limited relative rotation around the axis of rotation along different trajectories, corresponding to a rotating subregion. In order to facilitate its separate rotational orientation, the coupling member can be coupled to the post at different positions around its axis, and / or it can be inverted upside down.

By implementing the rotation restricting member to include a groove (the groove works together with the coupling assembly at the interface by a moving member when in use), a reliable non-fixed rotation restricting member can be set at a low price.

The action piece may be implemented as an intermediate component between the coupling components at the interface. Alternatively, the action member may be a component of the coupling assembly at the interface, such as a finger member.

Gracefully, the groove is a ball race and the moving member is a ball. In this way, inexpensive and well-functioning Nature, and can easily be made into an adjustable non-fixed rotation limiter.

The groove may extend less than 360 degrees around the axis of rotation and may, for example, form an annular segment. The coupling may include two or more such grooves, each having a different angular orientation with respect to the axis of rotation.

The groove may also extend 360 degrees or more about the axis of rotation, and may then, for example, form a spiral.

This creation is also about a coupling system that includes a pillar and an arm, and the coupling discussed above. The system can be sold in sets. In the assembled condition, the post interface can be coupled to the post, and the arm interface can be coupled to the arm.

The arm member may be provided with a recess for receiving the arm member interface of the coupling member. The arm member may, for example, include another coupling member for receiving a monitor.

The arm member may include an adjustable stop, such as one or more stop screws, which may be used to limit or prevent the ball from moving within the groove.

The post can be placed on the other arm. In this way, a reliable connected arm piece can be formed with great value for money, and can also be easily restructured, for example, by lifting the coupling piece from the post along the axis of rotation, relative to The post rotates to reorient the post, and push the coupling back down onto the post along the swivel axis.

In the case of a desk-mounted component, the post may be provided with a clip.

This creation is also about the monitor support, which contains At least one post member extending along a longitudinal axis, a monitor arm member for supporting the monitor radially outward relative to the longitudinal axis of the post member, and at least one coupling member discussed above, the monitor arm member is in use The coupling member is cyclically coupled to the pillar member at times.

The pillar of the monitor support can be implemented as a first pillar and / or an intermediate pillar.

The coupling can be reliably held in a hole in the arm of the monitor, such as a substantially annular hole, which at least partially surrounds the circumference of the post when in use.

It should be noted that the technical features described in each of the above paragraphs can be implemented independently in the coupling, the coupling system or the monitor support, that is, isolated from the contents of the paragraphs described further, and separated from the other paragraphs. The described features are combined with some of the features described in this paragraph or with only one or selected features of such a paragraph. In accordance with this disclosure, each of these features can therefore be combined in any way, but with any other feature described.

It should be noted that the drawings are merely schematic representations of preferred embodiments of the present invention. In the drawings, the same or corresponding components are represented by the same reference numerals.

Referring to Figures 1a and 1b, it is shown that the first embodiment of the present invention includes a coupling member (also Called bushing) 11. The coupling member 11 operates together with the pillar member 6 as a coupling component through the pillar interface 13, and operates with the arm member 9 as a coupling group through the arm interface 12. Pieces. The coupling member 11 is held in a substantially annular hole 10 surrounding the perimeter of the pillar member 6. The coupling member 11 includes a substantially cylindrical body portion that extends along the rotation axis A and forms a single-part bushing disposed between the column member 6 and the monitor arm member 9.

The pillar interface 13 includes a radially outer sleeve surface of the pillar 6 and a radially inner sleeve surface of the body portion of the coupling member 11. The arm piece interface 12 includes a radially outer sleeve surface of the body portion of the coupling piece 11 and a radially inner sleeve surface of the monitor arm piece 9. Both the post member interface 13 and the arm member interface 12 include a rotation restricting member, which restricts the rotary movement of the interface relative to its coupling assembly about a rotation axis A along the rotation axis A along with the rotation restriction member when in use. The longitudinal axis of the post 6 extends.

The rotation restricting member on the post interface 13 is a fixed rotation restricting member including a protruding member 14. The protruding piece is a protruding piece (also referred to as an extended protruding piece and a protruding piece protruding radially outward) 15 that extends radially inward from the inner sleeve surface of the coupling piece 11 toward the swivel axis A. The convex member 15 is configured to be coupled to a corresponding slot hole 7 in the column member 6 having a matching size, and the slot hole 7 also extends parallel to the rotation axis A.

The rotation restricting member on the arm piece interface is a non-fixed rotation restricting piece here, which is coupled with the monitor arm piece 9 having a limited rotation stroke in use, which allows the monitor arm piece 9 and the column to be Limited relative rotation between the pieces 6 around the axis of rotation A.

The non-stationary rotation restricting member includes a spiral groove (also referred to as a groove, a groove configuration and a track) 18 on the surface of the outer sleeve of the coupling member 11. The spiral groove 18 is borrowed during use. With the supervisor by action piece 19 The sight arm 9 works together. The spiral groove 18 is implemented as a ball race, which extends in a 360-degree spiral path around the swivel axis A and forms an annular segment. The action member 19 is actually a ball 20 that is held in a drop slot 21 at the hole (also referred to as a substantially annular hole) 10 of the arm member. With the non-fixed rotation restricting member formed by the ball 20 and the spiral groove 18, a limited rotation movement is provided in a rotation region corresponding to a single rotation about the longitudinal axis A.

Referring to Figures 2a, 2b, 2c, and 2d, the application of the first embodiment of the present invention is shown, which forms a monitor arm bracket (also referred to as a monitor support and a monitor bracket) that is actually a monitor table-type mount. ) 4. The monitor support 4 includes a post 6 that is provided with a clip (also referred to as a desk-type clip) 5. The clip 5 is mounted substantially in the middle of the rear side of the table 1. There is a mounting structure on the pillar member 6 carried on the clip member 5. This structure basically corresponds to the first embodiment discussed above, but the difference lies in the use of two protruding members 14 and two Slot hole 7. The post 6 on the clip 5 forms the first post 6 of the monitor arm support 4, and the lower arm 9 ′ can pass around the first post 6 by the first coupling member 11 ′. Coupling ground. The end of the lower arm member carries a second column member (also referred to as a middle column member and another column member) 8, and the upper arm member 9 ″ is swiveled around the second column member 8 by a second coupling member 11 ″. Coupled to form a connected monitor arm. The second coupling member 11 ″ is the same as the first coupling member 11 ′ (except for its height), and the second pillar member 8 is similar to the first pillar member 6 to match the second coupling member 6. Connector 11 ". The free end of the upper arm member 9 ″ carries the second post member 8 and the swivel bracket 3 carrying the monitor 2.

Fig. 2a shows a first configuration in which the spiral grooves 18 and the balls 20 of both the first and second coupling members 11 "and 11" work together for the upper and lower arm members 9 "And 9 'overlap to restrict rotation, that is, work together as an end stop against further rotation. This can be used to protect the back wall when the monitor 2 in front of the user is pushed away (see arrow D). The The clockwise movement of the lower arm member 9 ′ around the first pillar member 6 can freely reach 360 degrees, and the upper arm member 9 ″ can also move counterclockwise with respect to the second pillar member 8.

Fig. 2b shows the second structure corresponding to Fig. 2a, but the difference is that the first coupling member 11 'has been lifted away from the first pillar member 6, and connected to the lower arm member 9 'is rotated 180 degrees about the swivel axis A with respect to the post 6 together, and it is replaced on the post 6 and repositioned. The upper arm member 9 "has been adjusted by rotating it 360 degrees around the second post member 8 so that it overlaps the lower arm member 9 'again, but now both arm members 9' and 9" are positioned at The left side of the first post 6 replaces the right side of what they did in Figure 2a. The rotation restricting member now works together to restrict the rotation equal to FIG. 2a, that is, when the monitor arm member 9 is in front of the user, and the monitor 2 is pushed away. However, now the lower arm member 9 'can freely move 360 degrees counterclockwise around the first pillar member 6, and the upper arm member 9 "can also be moved clockwise around the second pillar member 8. The difference in the figure The condition can be seen by looking at the direction of the condition setter 25 and the arrow D. In this way, by restructuring and readjusting, the connected monitor arm bracket 4 can be set for a specific situation without using The tool may not require the use of different parts. Alternatively, the structure of Figure 2a can be used in the assembly In this case, the 180-degree repositioning is changed into a 180-degree readjustment step, and brought into the structure of FIG. 2b. In this case, the rotation of the lower arm member 9 'will not be restricted, but will give a free clockwise rotation movement, and will not be protected against movement to the rear wall.

FIG. 2c shows the third structure corresponding to FIG. 2a, but the difference is that the monitor arm holder 4 has been repositioned, and the clip 5 is at the left corner of the table 1. As an alternative to the clip 5, the table may be provided with a corner buckle mount. The structure is further different in that the upper arm member 9 ″ carried by the second pillar member 8 has lifted the second coupling member 11 ″ upward from the second pillar member 8 along the rotation axis. The second coupling member 11 is repositioned 180 degrees around the rotation axis A while the second column member 8 is rotated, and the second coupling member 11 "is pushed back along the rotation axis. The second pillar member 8 is restructured, and the upper arm member 9 "and the lower arm member 9 'no longer overlap, but will extend away.

The rotation restriction now works together to restrict rotation and protect the rear wall. The lower arm member 9 'can freely move 360 degrees clockwise around the first pillar member 6, and can also move clockwise around the second pillar member 8.

FIG. 2d shows a fourth embodiment corresponding to FIG. 2c, but the difference is that the structure is repositioned, and the clip 5 is at the right corner of the table 1. The structure is further different in that the lower arm member 9 ′ carried by the first pillar member 6 with the clamp member 5 has been lifted up from the first pillar member 6 along the swing axis A. A first coupling member 11 ′, repositions the first coupling member 11 ′ 180 degrees around the swivel axis A relative to the post 6, and the coupling member 11 along the swivel axis A Push down on the post 6 and restructure. The upper arm member 9 "carried by the second pillar member 8 on the lower arm member 9 'has been readjusted in the assembled condition. The readjustment has been performed by adjusting the rotation of the upper arm member 9" about the swivel axis A Positioning is completed up to 360 degrees. The lower and upper arm members 9 'and 9 "extend away as shown in Fig. 2c, but now they are oriented to the left instead of to the right as they did in Fig. 2c. The rotation restriction now works together to restrict rotation and The rear wall is protected. The lower arm member 9 ′ can freely move 360 degrees counterclockwise around the first pillar member 6 and can also move counterclockwise around the second pillar member 8.

Referring to Figures 3a and 3b, a second embodiment of the present creation is shown, in which the non-fixed rotation restricting member is formed at the pillar interface 13 by a slot 7 in the second pillar 8, the groove The hole 7 has an excessively large size in the turning direction, and receives the protrusion 15 to move. Together with the non-stationary rotation limiter formed by the perimeter groove 17 in the outer sleeve surface of the coupling member 11 at the arm piece interface 12, a rotation limiter with a compound stroke of 360 degrees can be obtained . When the lower and upper arm members 9 'and 9 "overlap, the rotation is restricted.

Figure 3b shows the second structure corresponding to Figure 3a, but the difference is that the upper arm member 9 "carried by the second pillar member 8 has been removed from the second pillar by the rotation axis A The coupling member 11 is lifted upward by the coupling member 8, repositioned to the coupling member 11 by 180 degrees about the rotation axis A relative to the second post member 8, and the coupling member is rotated along the rotation axis A. 11 is pushed down on the second post 8 and restructured. The rotation restriction now works together to extend the lower and upper arm members 9 'and 9 " Limit rotation when leaving without using tools or using the same parts.

Referring to Figures 4a and 4b, a third embodiment of the present creation is shown, in which the fabric has been turned upside down in terms of kinematics: the non-fixed rotation restricting member on the arm member interface 12 is included in the coupling member A radially outwardly protruding projection 15 on the outer sleeve of the body, the projection 15 cooperates with the oversized slot 7 in the arm member. The non-stationary rotation restricting member on the pillar interface 13 includes a peripheral groove 17 in the second pillar 8, and the balls 20 of the peripheral groove 17 are held in the inner sleeve of the coupling member 11. Drop in the slot 21. Similar to Figure 3a, when the lower and upper arm members 9 'and 9 "overlap, the rotation is restricted.

Figure 4b shows the second configuration corresponding to Figure 4a, but the difference is that the upper arm member 9 "carried by the second pillar member 8 has been restructured 180 degrees. Similar to Figure 3b, the The rotation restriction members now work together to restrict rotation when the lower and upper arm members 9 'and 9 "extend away.

Referring to Figures 5a and 5b, a fourth embodiment of the present invention is shown. This fourth embodiment is a variation of the first embodiment and includes a helical groove 18 having a fixing screw (also referred to as an adjusting stopper and a stopper screw) 23 as a non-fixed rotation restricting member . The arm piece 9 includes a track with two fixing screws 23 that can be used to limit the movement of the ball 20 in the spiral groove 18. The fixing screws 23 can be provided with a manually operated head so that they can be adjusted in a toolless manner. By locking the ball 20 between the fixing screws 23, the rotation restricting member can be adjusted reversely between the non-fixed position and the fixed position. As a simplification, a single fixing screw 23 may also be used. The end of the spiral groove 18 can be connected The second stopper is formed.

Referring to Figures 6a and 6b, a fifth embodiment of the present creation is shown in which the fabric is reversed again. Here, the slot 7 is provided in the arm member, and its size matches the convex member 15 extending from the coupling member body at its outer sleeve to provide a fixed rotation restricting member at the arm member interface 12. At this pillar interface 13, a rotation restricting member with a 360-degree compound stroke is provided. A first non-stationary rotation restriction member is provided on the top of the second post member 8 by a perimeter groove 17 (also referred to as a ring segment and a ball race). The first non-stationary rotation restriction member and the coupling body The action balls held in the surface of the inner sleeve work together. The perimeter groove 17 forms a circle segment of less than 360 degrees. A second non-stationary rotation restriction member is formed on the top of the inner sleeve surface of the coupling body by a perimeter groove 17, and the second non-stationary rotation restriction member also works with the ball. The ball 20 is held in place by a top flange (not shown).

Referring to Figures 7a and 7b, a sixth embodiment of the present invention is shown. Here, the slot 7 is provided in the upper arm piece 9 ″, the size of which matches the convex piece 15 extending from the coupling body at its outer sleeve to provide a fixed rotation restricting piece at the arm piece interface 12. At the post interface 13, a non-fixed rotation limiter with a travel of 270 degrees is provided, as indicated by arrow D. In this way, the second post 8 carries a finger 26, and the finger 26 and the The 270-degree slots in the top surface of the coupling member 11 work together. The finger 26 can be removed using screws 27 and can be repositioned to be held in the second post 8 where the finger 26 is held.
